What is a cyber threat intelligence platform?

A cyber threat intelligence platform collects, stores, and analyzes data about malicious files, infrastructure, and attacker behavior so security teams can make faster, more informed decisions. The core value is correlation: connecting a suspicious file to known malware families, infrastructure, and campaign history without requiring an analyst to manually pivot across multiple tools.In practice, a threat intelligence platform sits behind your existing EDR and SIEM and answers specific investigation questions. Is this file malicious? Have we seen this indicator before? Which machines are affec

How does a private threat intelligence platform differ from public tools like VirusTotal?

Public threat intelligence tools aggregate data from every organization that submits files, which means your uploads contribute to a shared corpus that any subscriber can query. A private threat intelligence platform keeps your file data inside an isolated environment so adversaries cannot study what you know, and your telemetry does not signal your detection capabilities to attackers.The operational difference matters most during active incidents. When you submit a sample to a public service, a sophisticated attacker monitoring that service learns you found their malware. A private vault appr

What is continuous malware analysis and why does it matter?

Continuous malware analysis means files are re-evaluated automatically whenever new threat intelligence becomes available, rather than only at the moment of first submission. A file that appeared clean six months ago can be re-scored today because a new YARA rule, a newly published IOC, or an emerging malware family connection now links it to known malicious activity.Most static analysis tools give you a verdict at upload time and stop there. That point-in-time model creates blind spots as the threat landscape shifts. Continuous analysis changes the relationship between intelligence and your f

What cybersecurity threat intelligence tools do SOC analysts use every day?

SOC analysts typically rely on a combination of hash lookup services, sandboxes, threat intelligence feeds, EDR platforms, and SIEM alerts to triage incidents. The practical bottleneck is correlation: each tool answers a narrow question, and stitching answers together manually consumes analyst time that could go toward actual investigation.Threat intelligence tools that reduce pivoting pay the biggest dividends in a SOC environment. When an analyst can take a single hash and immediately see related variants, historical prevalence, associated infrastructure, and a plain-language explanation of

How do threat intelligence feeds work in enterprise security operations?

Threat intelligence feeds are structured data streams containing indicators of compromise, including file hashes, IP addresses, domains, and malware signatures, sourced from security vendors, government agencies, ISACs, and internal research. Enterprise security teams ingest these feeds into their SIEM or threat intelligence platform to enrich alerts and identify whether known-bad indicators appear in their environment.The challenge with raw threat intelligence feeds is operationalization: a feed that delivers ten thousand IOCs per day is only useful if your team can automatically check those

What is a Private Vault in the context of threat intelligence?

A Private Vault is an isolated, encrypted storage environment where an organization keeps its own file telemetry, malware samples, YARA rules, and threat intelligence separate from any shared or public corpus. Files in a Private Vault are never exposed to other organizations or to adversaries who might monitor public submission services.The security benefit of a Private Vault goes beyond confidentiality. When your enterprise files are stored privately and continuously reanalyzed against global threat intelligence, you build a permanent historical record that supports incident response, complia

How does file prevalence help with alert prioritization?

Prevalence measures how commonly a file appears across endpoints in your environment and globally across a threat intelligence corpus. Files seen on nearly every machine in your organization are almost always benign system components. Files seen on only one or two endpoints, especially if they are also rare globally, deserve much closer scrutiny.Adding prevalence to your triage workflow gives SOC analysts a fast signal that cuts through alert noise without requiring deep analysis of every file. When Stairwell continuously recalculates both local prevalence (within your enterprise) and global p
